Letters Patent No. 99,521, dated February 8, 187

IMROVEMENT 1N PUMPS.

` The Schedule referred to :Lu these Letters Patent and making part of the same.

To all whom 'it may concern.-

Be it known that I, J oHN S. BARDEN, of Providence, county of Providence, and 'State of Rhode Island, have invented certain Improvements in House- Pumps; and do hereby declare the following Vto be a fnll, clear, and exact description thereof, reference being hadftothe accompanying drawings, in which- Figure 1 is a vertical section of my vimproved pump. n

Figure 2 is a detailed View of .ring for holding removable cylinder inplace. i

Figure 3 shows open or slotted barrel, cast in one piece. l

The object of my invention is an improvement on pump patented by myself', March 3, 1868.

The.l invention consists in a number of improvements, all tending to increase the efficiency of the mechanism, as will' hereinafter more fully'appear.

. 1n the drawings- A is the barrel of the pump, having open places A in its` straight part below the hose.

N is a removable cylinder. Any metal maybe used, but I prefer' glass, as o'ering the least amount of friction.

This cylinder rests upon packing b at the lower end of the barrel.

At the top of the cylinder is `placed packing c, upon which ring `S rests.

S has three arms, d (Two or more may be used, but three are convenient.)

After the ring S is pu't in upon the packing c, by passing the lugs l, for which purpose notches E E are :cut in ring S', the ring, with its arms, is turned so that the arms hold snugly against the lugs l, but the arms are a little above the lugs. l

The rings is then placed upon the arms 'd d, and

substantially as described.

2. The barrel A, 'cylinder N, upper and lower pack-I packing a upon ring S. Upon this packing is screwed the ring g.

The ring g then w,holds the cylinder in place. It also, by means of lip h, keeps the band k upon the barrel of the pump, and allows it to turn freely.

The handle of the pump attaches toband la, and it is desirable to have the handle movable from one side to the other. This is not` new, however.

The piston-valve V has weight m. 'lhe object of this is to preserve a perpendicular position, at all times, of the valve V, and to keep it at the right angle, relative to the cylinder of t-he valve.

A great advantage issecured by casting the barrel A in one piece, as regards expense in casting and f1tting up, and I claim casting a pump-barrelinone piece, to be new.

I am aware that removable cylinders, especially glasshave been employed in various waysin the steam-gauge, for instance; but ,Iam not aware that a removable cylinder has been combined with an open or slotted pump, cast in one piece.

What I claim, therefore, as my invention, and desire' to secure by Lett-ers Patent, is*- 1. The barrel A, cylinder N, lugs l, rings g S', and supports d, all constructed, combined, andy arranged ing-iings, supports el, and rings g S', all constructed and arranged substantially as set forth.Y

In testimony whereof, I have signed my name to this specification, in thepresence of two subscribing.

witnesses.
